The Secondary School Certificate examinations for four subjects that were suspended by the Dinajpur Education Board due to question paper leaks have been rescheduled hours after the announcement of new dates.
The exams will now take place between Oct 10 and Oct 15.
Earlier on Thursday, the authorities said the math, physics, agricultural science and chemistry exams would run from Oct 10 to Oct 13.
But a revised timetable was published on the board's website two hours later at 3 pm.
According to the latest schedule, students will take the math exam on Oct 10 followed by agricultural science on Oct 11, chemistry on Oct 13 and physics on Oct 15.
The timing of the two-hour exams, from 11 am to 1 pm, remained unchanged.
The change in the schedule has resulted in the postponement of practical exams. These will now be held from Oct 16 to Oct 20.
The decision to postpone the exams was made after the authorities found the question papers for the four subjects at a school in Kurigram's Bhurungamari.
The assessments were originally slated to run between Sept 22 and Sept 26.
